CFL Verification Testing Summary
- 424 models tested
from Jan 2010-Apr 2014
- Note products could have
experienced a marginal failure
- n one test and a full failure on a
another test so they count as full failures

Products failing one or more tests
- Marginal failure was defined
in CFL 4.0 as one sample exceed the allowable failure rate for one test.
– E.g. 2/6 samples failed rapid cycle when the spec requires 5/6 to pass – Marginal failure triggers elective retesting.

The interim life test looks at how many units are operational at 40% of the lamp’s rated lifetime claim. Note 1 unit failure is considered a pass and 2 unit failures is a marginal failure which allows for elective retesting.

Interim Life Failure Results
- Of the 61 models that failed interim life 27 fully failed only
this test
– 9 failed interim life and marginally failed another test
- We’ve had sample sets with 0 surviving lamps
– (0 out of 20 in batch 4)
- 20 models had 50% or less of their samples survive
- 12 models had 25% or less of their samples survive
